Keep running a method until I have enough arguments.

arg_stomp.py

#!/usr/local/bin/python3

import inspect
import random


class Foo(object):
    def a_method(self, x, y, z):
        print('Your method ran:\n', x, y, z)

if __name__ == '__main__':
    a_class = Foo()
    args = []
    kwds = {}

    while True:
        try:
            a_class.a_method(*args, **kwds)
            break

        except TypeError:
            your_params = inspect.getargspec(a_class.a_method).args
            args.extend([random.randint(1, 100) for x
                         in range(0, (len(your_params)-1))])  # ignore the `self` of the method
            print('Your params are:\n{}'.format(your_params))
            continue
